摘要:
A process for producing novel aldol derivatives of the formula, ##STR1## wherein C=W is a carbonyl group or a protected carbonyl group which comprises reacting a compound of the formula: ##STR2## wherein C=W is as defined above in the presence of an acid or a base at a temperature ranging from -70.degree. C. to room temperature. The novel aldol derivatives of the above formula are useful as intermediate for producing methanoprostacyclin derivatives which are useful medicines for prevention of thrombosis.
